Salt Chlorine Generators
The Best Chlorination Method Available. Here’s Why It Still Fails.
? Apple Podcasts ? Spotify

Salt chlorine generators are genuinely the best residential chlorination method available. The chemistry is sound, the convenience is real, and the results — when managed correctly — are excellent.

So why do so many salt pools look terrible? This episode is the full picture — how the technology actually works, what the industry consistently gets wrong, and what a properly managed salt pool looks like.

In This Episode
01
How the Cell Actually Works
Electrolysis, sodium hypochlorite, and why more salt does not mean more chlorine. The electrochemistry explained plainly.
02
Why pH Keeps Rising on Salt Pools
The hydrogen gas byproduct, CO2 off-gassing, and why salt pools need a lower alkalinity target than traditional chlorine pools.
03
Cell Output and Demand
Why a cell running above 80% is a warning sign, not a solution. What drives chlorine demand and how to get ahead of it.
04
What Kills Cells Early
Scale formation, low salt concentration, high output percentage, and the LSI connection. Why cell life is a chemistry problem, not a hardware problem.
05
AOP — The Best Complement to Salt
Advanced Oxidation Process systems combining UV and ozone. Why this combination outperforms either technology alone — and why it is the preferred setup.
What You’ll Take Away
  • The correct salt target range and why a digital meter is the only reliable way to test it
  • Why salt pools need alkalinity at 60-80 ppm — lower than the standard recommendation for traditional chlorine pools
  • What cell output percentage tells you about your system’s health and demand
  • The connection between LSI, scale formation, and premature cell failure
  • Why adding more salt when chlorine is low is not just ineffective — it can make things worse

My Pool Guy Is Full of Crap
Five things a credentialed pool chemist used to say before the science caught up. A confession from someone who should have known better — and eventually did.
